Patents by Inventor Frank Marvin Toth

Frank Marvin Toth has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method and apparatus to diagnose mechanical problems in machinery
    Patent number: 7225109
    Abstract: A method and apparatus for detecting mechanical problems in machinery used in a process. A model of the process is developed using a modeling technique such as advanced pattern recognition and the model is used to generate predicted values for a predetermined number of the operating parameters of the process and vibration parameters of the machinery. Statistical process control methods are used to determine if the difference between the predicted and actual measured values for one or more of the parameters exceeds a configured statistical limit. A rule set is used to indicate an actual or probable fault in the machinery.
    Type: Grant

    Date of Patent: May 29, 2007
    Assignee: ABB Inc.
    Inventors: Donald Karl Frerichs, Frank Marvin Toth, Steven James Johnson
  • Method and apparatus for detecting faults in steam generator system components and other continuous processes
    Patent number: 7113890
    Abstract: A method and apparatus and for detecting faults in components of a continuous process such as a steam generator. A model of the process is developed using a modeling technique such as advanced pattern recognition and the model is used to generate predicted values for a predetermined number of the operating parameters of the process. Statistical process control methods are used to determine if the difference between the predicted and actual measured values for one or more of the parameters exceeds a configured statistical limit. A rule set is used to indicate an actual or probable fault in a component of the continuous process.
